This tutorial provides a step-by-step guide for flashing the S19 miner using an SD card. By following these instructions, you will be able to update the firmware of your S19 miner using this method. Ensure that you have the necessary hardware tools and software before proceeding.

Tools Needed

Before you begin, make sure you have the following tools ready:

  1. Hardware: Computer (running Windows), TF card reader, TF card.
  2. Software: Decompression tool (such as WINRAR), S19 card firmware.

Steps for Antminer S19 Flashing

Step 1: Preparing the Tools

  1. Download the S19 card firmware from the provided link and save it on your computer.
  2. Unzip the downloaded firmware file using a decompression tool. Right-click on the file, select “Unzip File” and confirm if prompted.
  3. Insert the TF card into the TF card reader, and then plug the card reader into a USB port on your computer.
  4. Your computer will detect the TF card as a new device and assign it a disk letter (e.g., E:). Make a note of this disk letter.

Step 2: Formatting the TF Card

  1. Format the TF card to the FAT32 file system. To do this, right-click on the TF card’s disk letter (e.g., E:) and select “Format.”
  2. In the format dialog box, choose FAT32 as the file system and click “Start” to begin the formatting process.
  3. If prompted, confirm the deletion of all data on the TF card. Make sure to backup any important data before proceeding.
  4. Wait for the formatting process to complete. Once finished, you will receive a confirmation dialog. Click “OK” to confirm.

Step 3: Copying Firmware Files

  1. Open the folder that contains the extracted firmware files.
  2. Copy all the files from the extracted folder to the root directory of the TF card (i.e., directly on the TF card without creating any additional folders).
  3. Once the copying is complete, verify that all the files have been successfully copied to the TF card.

Step 4: Flashing the Miner

  1. Power off the mining machine (or separate control board) and insert the TF card into the designated slot.
  2. Power on the mining machine (or control board). The indicator lights will go through a specific sequence:
    • The double lights will remain on for about 3-5 seconds.
    • The double lights will turn off for about 10 seconds.
    • The green light will remain on continuously.
  3. When the green light is continuously on, it indicates that the flashing process is complete.
  4. Power off the mining machine (or control board) and carefully remove the TF card by pressing it inward and then pulling it out.
  5. Power on the control board again, and let the mining machine boot up.
  6. Log in to the background of the mining machine to verify whether the current firmware version matches the card-swiped firmware version.

Conclusion

By following this step-by-step tutorial, you have successfully flashed the firmware of your S19 miner using an SD card. It is important to keep your miner’s firmware up to date for optimal performance and security.
